SPECIFICATION forming part of Letters Patent No. 517,280, dated March27, 1894.

i Application iiled November 21, 1892. Serial No. 452,722. (No model.)

T0 @ZZ whom it may concern.-

Be it known that I, HARRIS KAR?, of Norwalk, in the countylof Huron andState of Ohio, have invented certain new and useful Improvements inBedsteads; and Ido hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it pertains to make and use the same.

My invention relates to an improved bedstead that is extensiblewidthwise or laterally.

My invention consists more particularly in suitable mechanism wherebythe bed-stead can be extended, as just indicated, by one operation, andmy invention consists also in certain features of construction and incombination of parts hereinafter described and pointed out in theclaims.

A preferable embodiment of my invention is shown in the accompanyingdrawings, wherein- Figures 1 and 2 are views in perspective of myimproved bed-stead, Fig. 2 showing the same extended. Fig. 3 is a sideelevation of the head-board looking at it from the outer side, partiallybroken away to show a portion of the mechanism employed in extending thebed-stead. Fig. 4 is a vertical section of the foot-board on line 4-4,Fig. 1. Fig. 5 is a top plan in horizontal section on line 5 5, Fig. l.Fig. 6 is a central vertical section of the head-board on line 6-6, Fig.l. Portions in Figs. 5 and 6 are broken away to reduce the size of thefigures. Fig. 7 is a view in perspective in detail, and Fig. 8 is atransverse section on line 8 8, Fig. 7, to more clearly show theconstruction.

Referring to the drawings, A represents the head-board of my improvedbed-stead. B the foot-board, O the side-board and B the legs of the headand foot-boards provided with casters B2. The head and foot-boards arecomposed of three sections 1, 2 and 3, the central section 2 beingprovided at each side of the central solid portion 4; of the same, witha mortise or pocket 5, to receive the end sections l and 3.

Side-boards C are secured to the respective end-sections 1 and 3 of thehead and footboards in any well known manner. The endsections of thehead and foot-boards, near their lower ends, are provided with a bar G(see Figs. 7 and 8) extending transversely of the end-sections andarranged in a horizontal plane, said bars being rabbeted at the topalong the forward edge, as at 7, the tongue or tenon 8 thus formed atthe forward edge nicely fitting a groove, 9, in a bar, 10, that eX tendsin under bars 6 of end-sections l and 3, and at its rear edge is rigidlysecured to the central section 2. Groove 9 extends from end to end ofparts lO to enable parts 6 to slide endwise of parts lO when theend-sections of the head vand foot-boards of thebed-stead are drawntoward, or away from, each other in or out of the mortises or pockets inthe central section as required in reducing or enlarging the size of thebed-stead, and bars or members 6 of the end-sections are, of course,reduced in width or cut away at the' rear edges from a point 11 neartheir outer ends to their inner or opposite ends to accommodate theadditional thickness of the central section.

The construction just described is shown very clearly in Figs. 7 and 8.Bars 6 and lO constitute the supports for the spring mattress.

With my improved bed-stead the spring mattress would also preferably bemade extensible and in addition to one stued mattress nicely fitting thebed-stead when the latter is in an unextended condition, additionalsections or pieces of stued mattress would be kept on hand 1for. usewhen the bed-stead was extended, and such additional mattress sectionscould be conveniently kept, or stored away, when not in use, in a drawerprovided underneath the bed-stead.

The construction of the head and foot-board sections of the bedstead isVery clearly shown in Figs. 4, 5 and 6.

The construction of the head and footboards are alike in that both arecomposed of sections as already described and in that the end-sectionsin both are adapted to slide easily in and out of the respective mortiseor pocket of the central section, said pockets or mortises beingsufficiently larger than the end-sections to enable the latter to slidein and out of their respective mortise or pocket without frictionbetween the opposing sides and top-edge of the end-sections and theopposing walls of the mortise or pocket of the central section. To causethe end-sections,

ICO

however, to slide nicely Within the central section, I attach to theouter portion of the top-wall and a small portion of the side-walls ofthe pockets or mortises of the central section, a piece of felt, orother suitable fabric, and attach to and at or near the inner extremityof the end-sections veneer, cloth or anything, to cause the end-sectionsto slide nicely, and without shaking or vibrating within the centralsection. Such construction will readily be understood withoutillustration, the object being to prevent the varnish or finish of theend-sections becoming marred or scratched in drawing the same in or outof the central section, and at the same time avoid any vibration of theend-sections within the central section.

Referring now to the means and mechanism whereby the end` sections ofthe head and foot-boards are drawn toward and from each other, in andout of the central section, to enlarge or reduce the size of thebed-stead, I would first remark that the central section is provided, asuitable distance from its lower end, with a slat or bar 12, thatextends through a slot or hole, 13, in the central solid portion ofthecentralsection, being rigidlysecured to said solid portion in anysuitable manner. Slat or bar 12, extends, in opposite directions intorecesses or chambers 14in the end-sections. (See Figs. 3 and 8.) Slat orbar 12 extends somewhat outside of thecentral section, as at1`5,(seedotted lines Figs. 3 and 5) and thereby forms stops to limit thedistance that the end-sections can be slid into the central section.Slats or bars 12 at one side, both top and bottom, are rabbeted, as at16, for receiving horizontal rack-bars D with one of which eachend-section is provided, said rack-bars being secured to the respectiveend-section in any suitable manner, exten ding through recess or chamber14 in the respective end-section into the cen tral section and throughhole 13 in solid portion 4 of the central-section. Chambers or recesses14 are ,just large enough in cross-sec tion to accommodate rack-bars Dand receive the rabbeted slat or bar l2 of the central-section and therack-bars are made to nicely lit the respective rabbet, the rack-barsbeing reciprocated, by mechanism hereinafter described, endwise of therespective rabbet or slat or bar 12 of the central section, therebymoving the end-sections, (to which the rack-bars as already indicatedare rigidly secured) out of or into the central section according to thedirection in which the rack-bars are actuated.

It will be observed that the rack-bar of one end section is adapted tooperate endwise of the lower rabbet in bar or slat 12 and that therack-bar of the other end-section is adapted to operate endwise of theupper rabbet in said slat or bar.

Racks D of the end-sections of both the head and foot-boards are in meshwith spurgear E located between the racks of the pairs of racks andcentrally of the solid portion 4 of the central section of said boards.Said gears are operatively mounted on a shaft e that extends from end toend of the bed-stead and has suitable bearing in the solid portion ofthe central section of the head and footboards, extending also throughmembers 10 and 12 of the central section of said boards. The one end ofthe shaft, preferably that end that has bearing in the foot-board of thebedstead, terminates at the outer side of said board in a squareportion, e', for the reception of a crank or suitable device forrotating the shaft.

By the construction hereinbefore described it will be observed that theend-sections of the head and foot-boards are slid into or out of thecentral section of said boards according as shaft e is turned in the onedirection or the other. The head-board, however, being considerably7larger than the foot-board, it is advisable to duplicate racks D andgear e of the operating mechanism within said board, and a preferableconstruction is shown in Fig. 6, that exhibits a central verticalsection of the headboard and also inFig. 3, wherein portions are brokenvaway vto exhibit the operating mechanism. Upon reference to thesefigures, it will-be observed that the end-sections of the headboard, asuitable distance above racks D, are provided with another pair of racksD and that the central section of said board is pro vided Withanotherslat 12"@d at .a corresponds ing elevation and rabbeted to receive racksD', all arranged and constructed substantially as slat 12 and racksDalready described. The upper pairof racks meshes with a gear, F,operatively mounted upon a spindle or shaft f, supported within thecentral section, di rectly above gear E, and said gears are operativelyconnected with each other by an endless chain G leading oversprocket-wheels g operatively mounted upon the gearsupporting shafts eand f.

17 represents slats (see dotted lines Fig. 5, and solid lines Figs. 4and G) that hold the operating racks in place. Said slats being rigidlysecured to the respective end-sections in any suitable manner, andmortises or pockets '5 of the central section are laterally enlarged forreceiving said slats of the end-sections, the inclosing casing for thislateral enlargement of the mortises or pockets of the central sectioncomprising preferably a single piece, 18, extending from end to end ofthe central section and perforated or recessed laterally, as at 19, toaccommodate the location and operation of shaft e.

By the construction hereinbefore described, it will be observed that theoperating racks are adequately supported. The rack bars at their freeends (see Fig. 3) terminate inan untoothed or plain portion d, thatserves as a stop to limit the outward movement of the endsection towhich the respective rack is secured.

Although I prefer the construction herein shown and described on accountof its durability and efficiency, I would have itunder- VIGC IIO

stood that my invention is not in any Wise confined to saidconstruction, but

l. In a bedstead, the combination with a head and foot board made intelescoping sections having each a bar or slat secured thereto Whichextends into a recess or pocket in each of the outer sections, saidslats or bars rabbeted on the upper and lower edges, and racks securedto the under sections of the head and foot boards and fitted to slide inthe rabbeted edges of the Slat or bar, of a shaft extending through thebed longitudinally, and toothed gear Wheels on said shaft in position toengage the teeth of the tWo racks in the head and foot boards,substantially as set forth.

2. In a bedstead the combination with a head and foot board made intelescoping sections, having each a bar or slat secured thereto whichextends into a recess or pocket in each of the outer sections, saidslats or bars rabbeted on the upper and lower edges, and racks securedto the under sections of the head and foot boards, and fitted to slidein the rabbeted edges of the slat or bar, of a shaft extendinglongitudinally through the bed and having toothed pinions thereonadapted to mesh with the rack bars, a pair of rack-bars located abovethe first mentioned racks in the head of the bed, a toothed Wheel inengagement therewith, and means for communicating motion from the shaftto the last mentioned toothed pinion, substantially as set forth.

In testimony whereof I sign this specication, in the presence of twoWitnesses, this 24th day of October, 1892.
